Velt is a real-time collaboration platform delivered primarily as a client SDK (React components and framework wrappers) for adding presence, live cursors, comments, notifications, huddles, recordings, and live selection to applications. Its server-side surface is the Velt Data (REST) API at api.velt.dev plus signed, retried webhooks, letting backends read and write comments, users, organizations, folders, documents, notifications, and user groups programmatically.
